The improved electric advertising and demonstrating machine comprises a housing or casing 1 provided with a base plate or bottom 2. The casing is provided with a removable glass front 3 which may be removed through the top portion of the casing 1' by removing the upper frame strip 4. The back of the casing is closed by means of an ordinary hin ged door which is not illustrated.

Mounted in the front portion of the casing l a short distance inwardly or in back of' the glass front plate 8 is a display pauelor board 5 having provided in the upper central portion thereof an advertising window or display opening 6. Provided substantially in the middle portion of the panel 5 is a transversely positioned main arcuate or curved slot 7 which is slightly inclined as clearly illustrated in Figure 1. Provided n the panel 5 above the lower end of the main slot 7 is a vertically inclined auxiliary arcuate or curved slot 8. Also provided in the panel 5 above the upper end of the main slot 7 is a slightly inclined arcuate or curved auxiliary slot 9. Provided in the lower portion of the panel 5 are openings through which pipes or tubes 10 and 11 project from the rear chamber of the housing into the space provided between the glass front and the panel 5. The front end of the pipe 10 is curved upwardly and supports a liquid supply or feed cup or container 12 the body portion of which is transparent so that the demonstrating liquid may be seen through the cup. The front end of the pipe 11 is also bent upwardly and has supported there-rm a discharge cup or container 13 the body portion of which is also transparent so that liquid discharged into the cup may he viewed through the walls of the cup. As clearly illustrated in'Figure 1 the discharge cup or container 13 is at a slightly higher elevation than the cup or container 12 so that liquid discharged into the discharge cup 13 is per mitted to flow through the pipe 11 back to the cup 12 by means of a return pipe or tube of which connects up with the bottom of a I its upper end.

liquid supply chamber 16 provided in a chambered supporting base 17 which as clearly illustrated in Figure 7 is mounted upon a supporting bracketor'frame 18 fastened in the rear chamber of the housing 1. of the base section 17 is provided with a central opening 19. Thebase section 17 isseated in an outer shell or casing 20 which rests upon the top of the tablet bracket or support 18 and projects upwardly above the top of the base section 17.

' For the purpose of providing a reserve supply of demonstrating liquid a liquid supply bottle or tank 21 is provided and the neck of the bottle 212 s equipped with a cap 22. The top of the cap 22 is provided with an opening in which a sleeve or collar 23 is secured; The inner end of thecollar or sleeve '23 affords a valve seat at.24 (Figure 7) against which a valve 25 normally seats. The valve 25 is provided with a valve stem 26 which slidably projects through an opening ina cup or casing'27 which is secured on the inner side of the top plate of thecap 22 and projects into the neck of the bottle 21. The bottom plate of the cup 27 is provided with openings 28 to permit the liquid from the bottle to flow into the cup 27 when the reserve tank or bottle is inverted and positioned with the cap 22 thereof seated against the top plate of the supporting base section 17 Engaged around the valve stem 26 between the valve 25 and the end plate of the cup 27 is a coiled controlspring 29 which acts to hold the valve 25 in closed position against the valve seat 24 so that liquid fromthe bottle 21'passing into 1 1e cup 27 is prevented from flowing out of the bottleor tank. Rigidly secured in the base section 17 is an axially disposed pn or rod 30 provided with a'disc head 31 on The headed pin or rod 30 is so'positionedthat when the capped bottle 21 is inverted and seated upon the apertured top plate of the base section 17 the head 31 of the rod projects upwardly through the collar 23 and contacts the valve 25 causing the same to be moved into theopen position illustrated in Figure 7. With the valve 25 open it will be noted that liquid from the bottle 21 is adapted to flow through the openings 28 of the cup 27 and through the collar 23 into the chamber 16 of the base section from which the liquideis adapted toflow through the outlet pipe 15 to replenish the supply of demonstrating liquid in the supply cup or container 12 to compensate for the loss of the demonstrating liquid due to evaporation or othercauses during the operation of the demonstrating machine. For the purpose of holding the reserve bottle or tank 21 in position tightly against the base section 17 a clamping plate or hood 31 is engaged The top plate over the upturned bottom -of the bottle 21. The hoodor clamping plate 31 is provided with diametrically oppositewprojections or lugs 32. to removably receive the hooked ends 33 of a pair of retaining coiled springs 34'.

The lower ends of the coiled springs 34. are shaped to provide books 35 which are engaged through openings provided in opposite sidesof the tablet-bracketor support 18.1: a The improved machine is intended for the purpose of advertising anddemonstratingthe operation of an improved fountain-pen hav-- ing a transparentbarrel or body section36 which is adapted to be filled and emptied by. means of a plungermechanism- 37. In the showing of the fountain pen the closure cap for normally enclosing the projecting-head end of the plunger mechanism 37 is omitted to expose the head end of the. plunger mechanism to permit the same to be actuated by the demonstraiing machine. The lower or writing end of the fountain pen is provided with-a pen po nt 38 and with the necessary feed bar. The improved fountain pen is provided with the transparent barrel 36 to permit a charge of writing fluid admitted into the barrel to be readily seen through the transparent barrel so that a person using one of the fountain pens canreadily ascertain when it is necessary to refill the fountain pen.

For demonstrating purposes the fountain pen to be demonstrated is adapted to be removably held in position by means of a sup-' porting device or carrier comprising a bar or bracket 39 having integrally formed at right angles intermediate the ends thereof an outwardly projecting stud or arm 40.

Mounted on each end of the supporting bar 39 is an adjustable gripping clip or clamping member 41 controlledby clamping screws 42 by means of which an adjustable portion of the clip 41 may be adjustedwithrespect to a stationary portion of the'clip. The upa per gripping clip 41 isadapted to be engaged around a boss provided on the upper end of the fountain pen barrel while the lower gripping clip is adapted to be clamped aroundthe tapered section of the fountain pen barrel. The fountain pen is adapted to be secured in position on the holding bracket and said bracket is adapted in turn to be removablyengaged in position by directing the supporting arm40 through the main'slot 7 of supporting, sleeve 44 which is integrally formed on the upper end of a lever or arm 45. The lower end of the lever 45 is pivotally supported on aflpin or stub shaft 46'engaged in a bracket 47 secured onthe base 48 of an upright supporting frame 49. Connected to the lower portion of the pivoted lever 45 is one end of a control spring the opposite or lower end of which is secured to the frame base 48 as clearly illustrated in Figure 2. Secured on the inner end of the stub shaft 52 is a gear 53. The gear 53 is in rolling mesh with an arcuate or curved rack 54 which is supported rigidly upon the frame 49. Adjustably projecting through one end of the rack 54 is a stop screw 55 the inner end of which is positioned in the path of travel of the pivoted lever or arm 45 to limit the swing thereof. b

For the purpose of operating the pivoted lever 45 said lever has rotatably engaged on one side thereof a roller 56. The roller 56 has rolling contact with a control cam 57 which is secured on a cam shaft 58 journalled in suitable bearings provided on the frame Work 49.

-As clearly illustrated in Figure 3 the cam shaft 58 projects into a gear box or housing 59 and has secured on the rear end there of within the housing 59 a gear 60 which in mesh with a driving pinion 61. The pinion 61 is secured on a stub shaft 62 which is also journalled in suitable bearings in the gear housing or box 59. Mounted on the stub shaft 62 within the gear box 59 is a worm wheel 63 which is in mesh with a driving worm 64. The worm 64 is formed on a worm shaft 65 which projects from the gear box 59 and is connected with a motor driving shaft 66 by means of a coupling 67 as illustrated in Figure 2. The motor shaft 66 forms part of a driving motor 68 which is mounted in the rear portion or chamber of the machine casing 1.

lVhen the machine is operated by the motor 68 the control cam 57 will cause the pivoted lever 45 to swing back and forth from the full line position illustrated in Figure 2 into the full line position illustrated in Figure 5 causing the gripped fountain pen to be carried from a position over the filling cup or container 12 into a position over the discharge cup or container 13. As the lever 45moves from the filling position to the discharge position the gear 53 tracking over the rack 54 causes the fountain pen to be rotated through a complete revolution as indicated in the dotted line position of the fountain pen in Figure 1. The fountain pen is thus carried from one cup to the other for the purpose of drawing a supply of writ ing fluid from the cup 12 and then discharging the contents of the fountain pen barrel into the receiving cup 13. i

The filling and discharge of the fountain pen is accomplished by operating the plunger mechanism 37 by mechanical means which will now be described. Pivotally mounted on a stub shaft 69 supported on the upper portion of the framework 49 is a rocker arm or walking beam 70. Pivotally connected to the walking beam 70 to one side of the pivot point thereof is the upper end of a connect ing or operating rod 71 which slidably projects through a bracket arm 72 formed on the framework 49. The lower end of the connecting rod 71 is provided with a threaded shank or screw portion 73 having adjustably engaged thereon an adjusting nut 74 for the purpose of permitting a control coiled spring 75 to be adjusted. The coiled spring 75 is engaged around the connecting rod between the adjusting nut 74 and the bracket arm 72 as clearly illustrated in Figure 3. The spring 75 is provided for returning the walking beam to a normal position after the same has been operated. Engaged on the lower end of the connecting rod screw 7 3 is a forked bar or head 76 which slidably projects through a guide block 77 secured on the machine framework 49. Rotatably sup ported in the lower forked or recessed end of the guide block 76 is a roller 78 which is positioned to haverolling contact with the peripheral surface of a control cam 79 which is mounted on the cam shaft 56 for the purpose of governing the operation of the walk ing beam 70.

lnte 'rally formed on one end of the walking beam 70 is a bearing sleeve 80 having j ournalled therein a plunger depressing rod or arm 81 which projects outwardly through the partition slot 8 and has the outer end thereof formed to afford a flattened depressing head 82 which at a predetermined time in the operation of the walking beam 70 is adapted to be brought into contact with the head of the fountain pen plunger 37 to slidably depress or move the plunger 37 inwardly from the full line position illustrated in Figure 4 into the completely depressed position illustrated in Figure 2 for the purpose of causing a charge of the writing fluid from the filling or supply cup 12 to be drawn upwardly through the fountain pen feed bar into the transparent barrel 36 of the fountain pen to fill the same with a charge of writing fluid which is clearly visible through the transparent barrel Secured on the inner projecting end of the plunger depressing rod or arm 81 a passaged head 83 through which aguide wire or rod 84 slidably projects. The lower end of the guide rod 84 is pivotally connected in the lower end of the rack 54. The guide rod 64 slidably projects through the slotted head 83 of the plunger depressing arm 81 and serves to hold the head 82 of the depressing arm in substantially a right angled relation with the end of the head of the plunger 37 during a depressing operation of the plunger.

Integrally formed on the upper or opposite end of the walking beam 70 is a passaged cylinder or bearing member 85. Rotatahly engaged and projecting through the bearing rod or-arm 86 which projects outwardly through the partition slot 9 and has the outer end thereof shaped to provide an actuating hook 87 for engagement with the fountain pen plunger 37 beneath the head of the plung er for thepurpose of causing the. fountain pen plunger to be pulled outwardly. from the depressed full line position .of Figure 5 into the projecting dotted line positionillustrated in said figure for the purposeof causing the charge .ofwriting fluidinthe fountain pen barrel 36 to bedischarged outwardly through "the writing end of the fountain pen into the liquid receiving container or cup 13 when the fountain pen is in a discharge position as illustrated in Figure 5. Secured on the inner projecting end of-the plunger raisingarm 86 is a passaged block 88. Slidably projecting through the, block 88 is a wire or rod .89 the lower end of which is pivotally hooked in the upper end of the rack 54. The pivoted rod 89 projecting through the passaged block 88 of the plunger elevating arm EBB-serves to hold the hook 87 in.

proper position for raising the plunger 37 when the walking beam 70 is operated.

' lVhen the walking beam 70 is operated to move from the dotted line position of Figure 5 into the full line position the plunger raising hook 87 is so positioned that as the f-ountainpen is movedfrom the dottedline position ofFigure 5 into the full lineposi tion the plunger 87 is moved into engagement with the hook 87 with the head of the plunger positioned above the-hookto perinit the plunger to be pulled outwardly to cause the contents of the fountain pen barrel to be discharged into the receiving cup 13, when the walking beam swings from the full line position of Figure 5 back into the dotted line position of said'figure.

It will be noted that the-demonstrating machine is so constructed that the transpary. ent barrel plungerv type fountain pen is adapted to be carried from a filling position over the feed cup 12 intoa discharge positionover the discharge cup 13 andthat the fountain pen during its travel from one extremeposition to the other is caused-to rotate through a complete revolution topermitthe plunger head to be properly positioned at predetermined times tobe mechanically actuated by the depressing head 82 when the fountain pen is in a filling position and by the raising hook 87' when the fountain pen is in a discharge position. v The machine is thus adapted toact automatically to clearly demonstrate the filling and dis? charging operations of the improved tran's-, parent barrel plunger type fountain pen.

For the purpose of describing thevarious steps in theoperation of the fountain pen and for describing the novel features thereof an illuminable "isible movable sign mechthe a stub shaft 92 journalled therein. on the inner projectingend of the stub shaft anism is provided in the machine casing 1 behind the partition or panel 5 to permitva rious advertising and descriptive signs to be automatically moved in timed or synchronized relation Withthe operation of the demonstrating machine to cause appropriatede scriptive signs to be moved into an observable position behind the sign opening 6 of anel 5. T 1e advertising .or sign mechanism comprises a frame 90 which is rigidly secured on the upper end of the framework 49 and is provided with a bearing sleeve 91' having Secured 92 isthe hub plate93 of an octagonalor multi-sided i advertising or sign drum 94. Each of the platesor sides of the drum194 has theouter surface thereof provided with a sloganor' a descriptive clause or sentence which can be read throughthe panel opening 6 when a particular side of'the drum is brought, into registering position with said opening." The sign plates 95 are secured in position longitudinally on the exterior of the advertising or sign drum 94 and are preferablyconstructed of a translucent material to permit the same to be illuminated when de: sired by meansofan electric light bulb 96 which issupported in a socket 97 secured to aframe arm 98. I

The illuminating bulb 96 is positioned to project axially into the open endof the drum 94 as clearly illustrated in Figure2.

For the purpose of rotating the advertising sign drum'94 in timed relation with the different steps in the filling and discharging operations of the fountain pen the drum hub plate 93 has secured on the outer end. there ofa ratchet 99. For the purpose of operating the ratchet 99 a pawl arm 100 has one end thereof coacting with the ratchet teeth and the opposite end secured to the walking beam 70 to be operated thereby. The pawl arm 100 is so arranged that each timethe plunger depressing end of the'wa'lking beam 70 is ele-,

v'ated the advertising or sign drum is rotated apredetermined amount to bring one of the signs in register with the panel opening 6. Connected to the pawl arm 100 is one end of a control spring 101 the opposite end of which .isconnected to one end of a'pin or rod 102 arm 100 to be actuated thereby. It will thus be noted that each time the sign or descriptive matter is changed that the audible signal 103 will be operated. In case the audible signal is not desired the switch arm 105 may be disconnected from the pawl arm 100.

Attention is called to the fact that if desired an annunciator system such as a radio or phonograph set may be connected to be operated in timed relation by the walking beam 70 for the purpose of explaining the various steps in the demonstration of the fountain pen operation.

The improved electrical advertising and demonstrating machine has the mechanisms thereof enclosed in the casing l behind the demonstrating panel which is provided with the slots 7, 8 and 9 through which the pen carrier or holder and the plunger actuating members project. The panel 5 is also provided with the opening 6 through which the advertising and demonstrating signs may be viewed. Mounted in frontof the panel 5 is the liquid supply cup 12 and the liquid discharge or receiving cup 13with the cup 13 positioned at a higher elevation than the cup 12 to permit liquid discharged thereinto to be returned by gravity through the pipe 14 to the cup 12. The glass front plate 3 of the casing is adapted to be removed through the top of the casing when the top moulding 4 is open so that the fountain pen holder or carrying bracket 39 may be removed from the sleeve 51 by simply swinging the spring clamping arms 43 apart to release the holder 39 so that a fountain pen barrel may be engaged in position held by means of the clamps 41. For the purposes of demonstration the fountain pen cap is of course removed and the head'oap which normally encloses the projecting end of the plunger mechanism 37 is also removed from the fountain pen barrel. "With the fountain pen barrel engaged in the clamping clips 41 the screws 42 are tightened to tightly hold the fountain pen clamped in position. The arm or stem 40 of the holder 39 is projected through the slot 7 ofthe panel 5 and into the supporting sleeve 51 (Figure '3) until the outer ends of the spring clamping arms 43 snap over the holder 39 to hold the holder and the fountain pen supported in position with the fountain pen positioned in front of the demonstrating panel 5.

To start the machine a control switch for the driving motor 68 is closed thereby causing the motor to drive the operating mecha nisms by means of the gear members disposed in the gear box 59 to rotate the cam shaft 58 and the control cams 57 and 79 which are secured thereon. The control cam 57 coacting with the roller 56 causes the lever arm 45 to swing from the full line position of Figure 4 toward the full line position of Figure 5 causing the gear 53 to track over the rack 54. The movement of the lever 45 is adapted to carry the fountain pen back and forth from a filling position over the cup or container 12 into a discharging position over the discharge cup or container 13 with the gear 53 acting to cause the fountain pen to rotate through a complete revolution as indicated by the dotted lines in Figure 1 during the travel of the fountain pen from one extreme position to the other. The cam 57 acts to swing the lever 45 from the full line position of Figure 4 to the full line position of Figure 5 and is so constructed that the fountainpen is permitted to be held in a stationary position for apredetermined period of time at the extreme positions of travel. After the charge of writing fluid has been emptied into the receiving cup or container 13 the control spring 50 acts to return the lever 45 to its normal position and thereby carry the fountain pen back into the filling position.

The control cam 79 coacting with the roller 78 controls the operation of the walking beam or rocker arm 7 O which is timed to operate in synchronized relation with the travel of the fountain pen so that when the fountain pen is returned to the filling position as illustrated in Figure 4 the plunger 37 is in its outermost or extended position and the fountain pen barrel is empty. lVhen the fountain pen is in a position to be filled the head of the plunger 37 is brought in position beneath the depressing head 82 and with the operation of the walking beam from the full line position of Figure 4 into the dotted line position the depressing head 82 pushes downwardly on the plunger 37 thereby projecting the plunger into the fountain pen barrel 36 to cause a charge of writing fluid from the filling cup 12 to be drawn upwardly through the fountain pen feed bar into the ink chamber of the fountain pen barrel to fill said chamber as illustrated in Figure 2. The type of fountain pen adapted to be demonstrated by the machine of this invention is of the type disclosed in my copending application for patent for a fountain pen filed April 24th, 1930, U. S. Serial No. 446,807.

After the filling of the fountain pen barrel the control cam 79 acts on the walking beam to cause the depressing head 82 to be elevated as the fountain pen is carried by the pivoted lever 45 from the full line position illustrated in Figure 4 toward the full line position illustrated in Figure 5 cansing the fountain pen to be revolved through a complete revolution whereby the fountain pen as it approaches its extreme position of travel toward a discharge position the plunger head 37 is moved into engagement with the plunger elevating book 87 while the fountain pen is temporarily held stationary in the discharge position illustrated in Figure 5 ready to have the contents of the fountain pen barrel discharged. At this point in the operation the control cam 7 9 again acts on the walking beam 7 O to cause the same swingof the walking beam causes the pawl to swing from the full line position of Figure 5 into the dotted line position thereby causing the hook member to be raised to draw thefountain pen plunger 37 upwardly caus-' ing the liquid contents of the barrel 36 to be discharged into the discharge or receiving container or cup 13.

The sign carrying drum 94 which is mount: ed in the casingbehindthe, opening 6 of the demonstrating panel 5 isilluminated by the electric bulb 96 and is rotated a predetermined amount each time the plunger depressing end of the walking beam is moved from the dotted line position of Figure 4 toward the full line position. The'upward By means of the reserve liquid supply bot tle or tank 21 the demonstrating liquidin i the filling container or cup 12 is adapted to be replenished as required to compensate for evaporation of the causes. I
